Thus, when the interrupt occurs, the CPU sends a warning message to MMI(man machine interface)(5). Further, the terminal displays the warning message on an LCD(liquid crystal display) and outputs a warning sound to a speaker. The terminal finishes one minute after informing a user of the finish.

The global word line selection circuit has the first global decoder(120) for selecting a word line of odd global word lines and the second global decoder(100) for selecting a word line of even global word lines. The first local decoders correspond to the odd global word lines. The second local decoders correspond to the even global word lines. Each of the first and second local decoders has a plurality of drivers connected with the local word lines. Each driver a pull-up transistor connecting a local word line corresponding to a signal of a global word line with a row partial decoder(160), and a pull-down transistor a local word line to a block decoder(180) in response to a signal of a global word line.
